Known also as prep sinks, entertainment sinks and bar sinks offer an extra workspace for someone to help chop carrots, for wine to chill on ice or for washing hands before sitting down at the table. Multiple prep sinks have become popular in today's indoor or outdoor kitchens. Some are specifically designed for multiple chefs to be able to use a single area for prep in the kitchen. They add a unique style to the modern kitchen. Entertainment and bar sinks can be matched to the existing main sink in the kitchen, coming in a wide variety of materials, shapes and sizes.
